154 CASA GRANDE, ARIZONA [ETH. ANN. 28 
Their descendants ultimately joined the Zui and the Hopi, with 
whom, according to legends, they still live.! 
Historians have paid little attention to these migrations, for they 
occurred in prehistoric times, but vague legends still survive among 
both Zufi and Hopi bearing on the life of some of their clans in the 
south. These migration legends are supported by archeologic evi- 
dence and are supplemented by Pima traditions. 
One objection that has been repeatedly urged against acceptance 
of the traditions of the modern Pima that they are descendants of the 
inhabitants of Casa Grande is that the former do not now construct 
great massive-walled houses like the buildings here described, but 
Fic. 54. Typical modern Pima rectangular dwelling. 
live in thin-walled houses supported by posts. The Pima have 
not constructed habitations of the former type in historic times. 
The excavations in Compound B show that many fragile-walled 
houses of rectangular form once stood within this inclosure and there 
is goad evidence that they existed in the other compounds also. 
The people of Casa Grande, or at least some of them, inhabited the 
same kind of houses as the modern Pima. These great buildings 
are not habitations; they are sacred: edifices or communal citadels. 
But it may be objected that the typical Pima houses were round, 
1 These legends call for new researches on the character of the prehistoric culture along the northern 
tributaries of the Salt River, the Verde, the Tonto, and other streams. Accurate information on the fol- 
lowing, among other, points is needed: (1) What relation exists between the symbolism on pottery from 
these valleys and on that from the Gila and the Little Colorado? (2) Was cremation practised along 
the Verde and the Tonto in prehistoric times? Is there any evidence of cremation in ruins on the Little 
Colorado?
